Simulating a practical criminal case, six single hairs of the head from five individuals were sampled and analysed by the neutron activation analysis. Two samples which originated in the same person could be correctly selected by their analysis. As a method for hair individualization, Na, Cl, Br, and Mn in the samples were determined and examinations were made to see each element could be identified at matching limits of 10,25,or 50%. It was concluded that 25% was usually permissable as the matching limit in practical cases. For the permission of a value more than 50% as the limit, more elements such as Zn, Hg, and others must be determined and the results must be collectively considered. There were no remarkable differences between the concentration of trace elements in a single hair and in strands of hair from the same individual.
